Re: [libvirt] [PATCH] x86ModelHasFeature: avoid NULL-dereference for unmatched CPU "feature"

Here's another fix for a potential NULL-deref. x86cpuidFind can return NULL, yet this caller would dereference that pointer (via x86cpuidMatchMasked) without first checking. for (i = 0; i < feature->ncpuid; i++) { cpuid = feature->cpuid + i; model_cpuid = x86cpuidFind(model->cpuid, model->ncpuid, cpuid->function); - if (!x86cpuidMatchMasked(model_cpuid, cpuid)) + if (!model_cpuid || !x86cpuidMatchMasked(model_cpuid, cpuid))
